After inserting the rubber ring), form a strip at one end of this wire,
This invention relates to an electric wire processing machine in which a terminal is inserted and crimped into the strip portion.

(Prior Art) Generally, an electric wire W used for wiring as a wire harness for an automobile has an insulating jacket b coated on the outside of a core wire a, as shown in FIG. After inserting a rubber waterproof seal c into one end of this electric wire W, a strip part a1 is formed at one end of this electric wire W, and a connecting terminal d is inserted into this strip part a1 and crimped to attach it. It is something that

The means for attaching terminals and the like in this type of electric wire processing machine that has already been proposed is carried out in the order shown in FIGS. 8 and 9.

That is, as shown in FIGS. 8 and 9 a, b, c, and d, for example, an electric wire (lead wire) W used for wiring as a wire harness for an automobile
There are multiple (actually 8) electric wire conveying devices using rotary type rotating disks in electric wire processing machines.
Each clamp device is provided with a wire W cut to a predetermined length with a cutter (see Fig. 9a), and a wire W cut to a predetermined length is held by the outer sheath b of one end of the wire W as shown in Fig. 9b. A waterproof seal c made of a rubber ring of a certain length as shown is inserted into a predetermined position, and the outer sheath b of the electric wire W at the outer end of this waterproof seal c is
